The bosses 13 are integrally connectedwith the walls 2 by spaced flanges 17 extending from integral connectionwith the corners of said bosses to integral connection with the flanges7. The corner portions of the car floor are strengthened by integralflanges 18 extending from integral connection with the corners of thebosses 13 to integral connection with tle corners of the car floor.

The corners of the car body thus constructed are formed with integralbumper elements 19 to receive the shocks of colliding cars.

From the foregoing it is apparent that my improved car body is a unitarycasting in the form of a box-like structure of not much greater weight,if any, than the usual cars having wood floors or wood side walls. Thecar body is much stronger and much more durable than cars made ofassembled pieces and parts and may be manufactured with greater economy.Thus, many desirable results are obtained.

I am aware that the construction and arrangement may be varied withinequivalent limits without departure from the nature and principle of theinvention. I do not restrict myself unessentially but what I claim anddesire to secure by Letters Patent is 1.
